The keystroke intercept circuit is used in the computer-aided terminal scanner described in [*] to capture or inject keystrokes at the keyboard screen interface of a terminal. This circuit is computer-controlled by a system not associated with the terminal attached to the intercept circuit. The keystroke data captured or injected by the intercept circuit is stored in a fixed medium, such as tape or disc, by the computer control system. The intercept circuit has two modes of operation: record mode, or keystroke capture, and playback mode, or keystroke injection.
